Connection system for simultaneous bidirectional transmissions by optical fibre.

Abstract

Abstract According to the invention, the transmissions in a first direction between a first station 1 and a second station 2 are ensured by the transmission E1 and the guiding by an optical connection fibre fl of a light wave O1 of specified wavelength modulated by information SSI1 to be transmitted to the second station 2; and the transmissions in a second direction by the reflecting of a fraction O2 of the transmitted light energy 01 and the modulating of the latter by information SSI2 to be transmitted to the first station 1, this being done with the aid of a modifiable back-reflector ERM2 comprising a liquid crystal cell. The invention applies in particular to teledistribution networks.
